Definitions

  • the present invention relates to the incorporation of fibriform material comprising smoke-modifying agents in smoking material rods .
  • a filament comprising smoke-modifying agents be incorporated in the smoking material rod by insertion of the filament at the tongue of the garniture of a tobacco rod making machine.
  • insertion of a filament at the tongue of the garniture would inevitably require bending of the filament, which bending may be undesirable under certain circumstances, such as when a filament of lesser flexibility is used.
  • the precise location of the filament laterally of the resulting tobacco rod is not easily regulated and also, disadvantageously, the flow of tobacco at the garniture could be disturbed.
  • US 5,144,966 discloses a flavourant-release additive in the form of a filament for incorporation in the combustible filler of cigarette products and a method of production of such a filament.
  • the filament, on a reel module can be fed continuously to the moving cigarette wrapper strip in coordination with the combustible filler feed stream.
  • the cigarette wrapper strip is fed directly into the garniture of the tobacco rod making machine.
  • the present invention is predicated upon Applicant ' s realisation that it is important that when a smoke-modifying agent is incorporated in a tobacco rod such as to be distributed along the rod, the agent is located at an axial zone of the rod.
  • axial zone location of the agent ensures maximal transfer efficiency of the agent into mainstream smoke.
  • location of the agent at an axial zone of the rod ensures a minimal propensity of spot formation on the tobacco rod wrapper.
  • ash formation in cigarettes comprising a tobacco rod having a smoke-modifying agent at an axial zone thereof resembles that of conventional cigarettes.
  • US 4,219,031 teaches a method of making a smoking article, which smoking article comprises a gas permeable, self-supporting central core consisting essentially of a carbonised cellulose rod, which core is circumscribed by tobacco.

  • the present invention further provides, according to a second aspect thereof, a method of incorporating fibriform smoke-modifying material in smoking material rod, wherein fibriform smoke-modifying material is fed longitudinally thereof to a rod making machine, the feed path in said machine extending in the travel direction of the smoking material deposition run of the suction band of said machine, said fibriform material being constrained by guide means in said machine to follow said feed path spaced from said run of said suction band against the suction force towards said run until at a predetermined distance along said deposition run said fibriform material becomes supported and is subsequently maintained at a predetermined distance from said run by particulate smoking material deposited on said run, thereafter further said smoking material being deposited on said run.
  • the fibriform smoke-modifying material suitably takes the form of a single, continuous, fibriform element.
  • the fibriform smoke-modifying material could be fed to and into contact with the particulate smoking material in the form of a sequence of discrete fibriform elements.
  • each element, in the feed path of the elements may be at each end thereof in contact with the respective ends of the next adjacent elements of the sequence thereof, or may be spaced therefrom.

However, alternatively the feed rollers 11, 12 may be remote from the rod making machine 1 and thus the length of the feed tube 15 would be considerably longer.

Abstract

La présente invention concerne un procédé permettant d'incorporer un matériau fibriforme modificateur de la fumée dans une tige de matière à fumer. En l'occurrence, on alimente dans le sens de la longueur de la machine à cigarettes un matériau fibriforme modificateur de la fumée. Cet axe longitudinal de la machine à cigarettes correspond au sens de progression du chemin de dépôt de matière à fumer de la bande d'aspiration (3) de la machine. On peut choisir de faire contenir le matériau fibriforme (13) par des organes de guidage (15) dans la machine de façon à suivre un chemin d'alimentation présentant un certain écart par rapport au sens de défilement (31) de la bande d'aspiration en contrariant la force d'aspiration, en direction du sens de défilement. On peut aussi choisir d'amener le chemin d'alimentation du matériau fibriforme modificateur de la fumée à monter vers le chemin de dépôt sous l'influence de la force d'aspiration en direction de ce chemin, jusqu'à ce qu'à une distance définie le long du chemin de dépôt, le matériau fibriforme se trouve sur un support et reste ainsi maintenu à une certaine distance du chemin grâce à la matière particulaire à fumer (20) déposée sur le chemin. On continue alors à déposer un complément de matière à fumer (20') sur le chemin de dépôt.
